Read the following case and answer the question given below:
At a construction site, a worker uses a pulley to lift two cement bags to different floors of a building.
Bag \(A\) has a mass of \(20\ kg\) and is lifted to a height of \(5\ m\) above the ground.
Bag \(B\) has a mass of \(10\ kg\) and is lifted to a height of \(10\ m\) above the ground.
The site supervisor asks the worker to compare the energy stored in the two bags due to their positions.
Assume: \(g\ =\ 10 m/s^{2}\).
Bag \(A\) has a mass of \(20\ kg\) and is lifted to a height of \(5\ m\) above the ground.
Bag \(B\) has a mass of \(10\ kg\) and is lifted to a height of \(10\ m\) above the ground.
The site supervisor asks the worker to compare the energy stored in the two bags due to their positions.
Assume: \(g\ =\ 10 m/s^{2}\).
1. What is the gravitational potential energy of Bag \(A\)?
2. Which statement correctly describes the factors affecting gravitational potential energy?
3. A student says,
"Bag \(B\) has greater gravitational potential energy because it is lifted to a greater height."
Which statement best evaluates the student's claim?
4. The site supervisor wants to double the gravitational potential energy of Bag \(B\) without changing its mass. Which of the following actions should the worker take?
